To all whom it may concern Be it known that I, THOMAS Fnasnn JAMES, acitizen of the United States, and resident of Darlington, county ofDarlington, State of South Carolina, have invented certain new anduseful Improvements in Plows, of which the following is a specification.

This invention relates to plows, cultivators, and the like and forconvenience I will use the term )low in the eneric sense throughout theapplication.

One of the objects of the invention is to provide the plow with anadjustable share and a bar, substantially parallel with the draft beam,and arranged rearwardly of the share and adapted to be maintained insubstantially parallel relation with the draft beam for its differentadjustments.

Another object is to provide improved means for adjusting the positionof the share, this means being mounted on the draft beam and permittingthe adjustment while the share is in the furrow.

A further object of the invention is to provide means whereby theaforesaid bar may be adjusted vertically so as to be thrown out ofparallel relation with the draft beam, the means for adjustment beinglocated on the draft beam where it is readily accessible andconveniently operated.

The novel features of the invention will be apparent from the followingdescription, taken in connection with the accompanying drawings, inwhich Figure 1 is a side elevation of a plow embodying my invention;Fig. 2 is an enlarged fragmentary elevation with the parts shown in adifferent position from that shown in Fig. 1; Fig. 3 is a rearelevation; Fig. 4 is a perspective view of a detail.

Referring to the drawings, 10 indicates the draft beam, preferablyformed of two parallel bars which are secured together at their forwardend and spaced apart throughout the greater portion of their length.Handles 11 are secured to the beam 10 by means of a bolt 12, thesehandles being braced by means of bars 13 which permit the handles to beraised or lowered in the usual way. The brace bars 13 are secured to thebeam by means of a bolt 14. Pivotally mounted on the bolt 12 is adownwardly extending link 15 composed of two parallel bars spaced aslight distance apart throughout the greater portion of their length andSpecification of Letters Patent.

having secured to their lower ends, by means of a bolt 16, a share 17. Abar 18 having its forward end arranged between the bars constituting thelink 15 is pivoted to the latter by means of a bolt'19 and has itsrearward end pivoted to a pair of spaced bars constituting the link 20by means of a bolt 21. The bar 18 has a wearing shoe 22 secured to thelower side thereof by means of a bolt 23. As shown in Figs. 1 and 2, thelower side of the shoe 22 is substantially parallel with the beam 10 andin order to maintain this parallel relation the upper ends of the barconstituting the link 20 are pivotally arranged on the bolt 14. Thedistance between the bolts 19 and 21 is substantially the same as thedistance between the bolts 12 and 14 and also the distance between thebolts 12 and 19 is substantially the same as the distance between thebolts 1 1 and 21 so that the links 15 and 20 are substantially paralleland when swung on their pivots 12 and 14 maintain the shoe 22substantially parallel with the beam 10.

It is sometimes desirable in the use of the plow to have the shoe 22 outof parallel relation with the beam 10 and for this purpose the barswhich constitute the link 20 are provided with slots 24 through whichthe bolt 14: passes. A wedge member 25 having a handle 26 is pivotallymounted on the bolt lfb between the bars of the link 20 and when thiswedge member is swung to bring the thicker portion thereof between thebars, the latter are clamped against the bars of the beam 10, and whenthe wedge member is swung so as to bring the thinner portion thereofbetween the bars, the latter are released and the bars may be raised orlowered relative to the beam and then clamped in any position to whichthey are adjusted.

For the purpose of adjusting the angle of the share 17 I have pivotallymounted between the bars constituting the beam 10 a hand lever 27provided with a latch device 28 of any suitable construction, this latchdevice cooperating with a suitable quadrant 29 to hold the lever in anydesired position. The lower end of the lever 27 is connected with thebars of the link 20 by means of a link 30 and as will be readilyunderstood from the drawings, this construction permits the links 15 and20 to be swung to different positions by moving the lever 27 By havingthe lever 27 extend above the beam 10, it is in a position where it isreadily accessible and permits adjustment of the angle of the sharewithout removing the plow from the furrow. Furthermore the adjustment ofthe link 20 can also be accomplished while the plow is in the furrow.

Having thus described the invention what is claimed and desired to besecured by Letters-Patent is,

1. In a plow, the combination of a draft beam, a pair of downwardlyextending links pivoted to said beam, the pivotal connection of one ofthe links being adjustable to permit raising and lowering of the linkrelative to the beam, a bar pivoted to the lower ends of said links andnormally arranged substantially parallel with said beam, a hand leverpivoted to said beam and extending thereabove, a link connected with thelower end of said lever and one of the first mentioned links, and meansfor locking said lever in different positions.

2. In a plow, the combination of a draft beam, a downwardly extendinglink pivoted to said beam, a bar pivoted to the lower end of said linkand extending rearwardly thereof, a link pivoted to the rearward end ofsaid bar, a pin and slot connection between the latter link and saidbeam, and a rotatable wedge on said pin for securing the link to thebeam.

3. In a plow, the combination of a draft beam, comprising two barsspaced apart at their rearward ends, a downwardly extending linkpivotally arranged between said bars, a bar pivoted to the lower end ofsaid link and extending rearwardly thereof, a link having its lower end.pivoted to the rearward end of said last mentioned bar and its upper endarranged between the bars of said beam and having a longitudinal slottherein, a bolt carried by said beam and extending through said slot,and a rotatable wedge member arranged on said bolt and adapted to clampsaid link to the said beam.

In testimony whereof I affix my signature in presence of two witnesses.
